This application provides a kind of embodiment of lamp bead.

The lamp bead includes multi-group light-emitting point, wherein：Every group of luminous point includes at least one monochromatic luminous in multi-group light-emitting point Point, each monochromatic luminous point are used to send a kind of primary lights, and every group of luminous point is used to send one group of primary lights, wherein, Duo Zufa The color combination of every group of luminous point is identical in luminous point, and color identical luminous point sends the peak of primary lights in multi-group light-emitting point Value wavelength differs.

Fig. 1 is according to a kind of schematic diagram of optional lamp bead of the utility model embodiment, as shown in figure 1, the lamp bead is LED lamp bead, the multi-group light-emitting point that the LED lamp bead includes are multigroup chip 10, and each luminous point is monochromatic brilliant in multi-group light-emitting point Piece.Multigroup chip 10 can include first group of chip, 11, second groups of chips 12 ..., to N group chip 1N, wherein, N is big In the natural number equal to 1.

Every group of chip in multigroup chip is used to send one group of primary lights, wherein, every group of chip includes at least one monochrome Chip, each monochromatic chip are used to send a kind of primary lights.

The color combination of every group of chip is identical in multigroup chip, and color identical chip can be sent in multigroup chip The peak wavelengths of primary lights differ, for example, multigroup chip includes first group of chip and second group of chip, first group Color combination in chip and second group of chip is red, green and blueness, but the red chip in first group of chip and The peak wavelength for the primary lights that red chip in second group of chip can be sent is different.

Alternatively, lamp bead can be LED lamp bead, and chip effect is to be used to light in LED lamp bead, and LED principle of luminosity is Semiconductor (chip) is electrically excited and lighted, and the composition of chip determines the spectral energy distribution curve of the light sent, therefore, choosing Select and control the spectral energy distribution curve for the light that the i.e. controllable chip of the composition of chip sends.If lamp bead is LED lamp bead, Each monochromatic chip in multigroup chip is used to send a kind of primary lights, then the control circuit of control is performed to lamp bead to be set Each monochromatic chip is set to processor to be connected, wherein, processor is used to control respectively each monochromatic brilliant in multigroup chip Piece is luminous or closes, that is, each monochromatic chip can individually be controlled whether to light by processor, every group of chip passes through processor Control cause lamp bead is sent to need the color that shows.

Alternatively, lamp bead can also be non-LED lamp bead, and each luminous point is used to sending light, the material of each luminous point into Divide the spectral energy distribution curve for determining the light that can be sent.

Fig. 2 show the schematic diagram of the spectral energy distribution curve for the light that two panels color identical chip can be sent, light Spectral power distribution curve is the relation curve between the wavelength of light and energy, and energy can refer to luminous intensity or radiance Equiscalar, although the color for the primary lights that two panels color identical chip can be sent is identical, in Fig. 2 it can be seen from The peak wavelength of two curves is different, and two crests are adjacent but misaligned, the position of the coincidence point of two crests by two monochromes Chip determines.

Specifically, the mode for choosing chip can be according to the requirement of receiving terminal spectral.Receiving terminal can be spectral formula 3D glasses etc., receiving terminal can the light of two kinds of curves of pair display simultaneously gate, gate the light in the range of preset wavelength, make One of which light most of energy by and shielding the light outside preset wavelength scope.Can first it be determined when choosing chip The coincidence degree of two crests, so as to carry out conditional selection to two chips.Color identical chip is sent in multigroup chip Primary lights spectral energy distribution curve joining wavelength corresponding to energy be no more than predetermined threshold value, alternatively, in advance If threshold value is 5% of minimum peak luminous intensity in the spectral energy distribution curve of color identical chip, for example, two groups Lighted in chip corresponding to the wavelength of the coincidence point of the spectral energy distribution curve for the light that the wafer of color identical two is sent strong Degree is no more than 5% of minimum peak wavelength in two peak wavelengths, it is necessary to which explanation, the selection of peak wavelength are not limited to figure Form or the example above in 2.

Multigroup chip can be encapsulated in lamp bead, for example, as shown in figure 3, two groups of monochrome wafer packages are entered into a lamp bead Interior, multigroup chip can encapsulate by way of common cathode encapsulates or common anode encapsulates, and each monochromatic chip is individually controlled System.Alternatively, multigroup chip can be encapsulated in lamp bead by surface mount process.

Alternatively, multigroup chip can be arranged into array, and every group of chip is distributed in a row or column of array, such as Fig. 3 institutes A kind of embodiment of the encapsulation top view of the lamp bead of dual spectrum is shown as, each color has two chips, and the of two chips One is classified as first group of chip, including red chip 101, and green chip 111 and blue dies 121, second is classified as second group of chip, Including red chip 102, green chip 112 and blue dies 122 are, it is necessary to which explanation, the form of encapsulation are not limited in Fig. 3 Shown spread pattern.Wherein, in first group of chip and second group of chip the light that color identical chip can be sent peak value Wavelength differs, and three kinds of monochromatic chips are all chosen according to the requirement of above-mentioned spectral and finally encapsulated to a LED lamp In pearl, make lamp bead that there is the characteristics of monochromatic multiple spectrum, the lamp bead is full-color LED lamp bead, can send three kinds of bases of RGB The light of color, also, each is monochromatic by two kinds, or the chip of two or more different dominant wavelengths can be used to form, it can send The monochromatic light of different dominant wavelengths, so as to realize that spectral formula lights.

The lamp bead that the embodiment provides sends color by multigroup chip and combines the combination of identical primary lights, and different groups are brilliant The spectral energy distribution curve for the primary lights that color identical chip can be sent is different in piece, and peak wavelength is also different so that Lamp bead can send the light of multiple spectrum, be applicable to the luminous product of spectral formula.
